What I'm looking for

I am looking for opportunities that foster innovation and collaboration, where I can leverage my blockchain expertise to drive impactful projects.

With over six years of experience in the blockchain industry, I have honed my skills in developing innovative cross-chain and Layer 2 solutions. My journey has taken me through various roles, where I have specialized in Decentralized Finance (DeFi) platforms, DAOs, and tokenomics. I am passionate about creating robust and secure blockchain infrastructures that drive efficiency and innovation.

In my recent role as a Senior Blockchain Engineer at StripChain, I architected a cross-consensus communication protocol that enables the development of omnichain applications. My work involved integrating multiple chains, including Ethereum and Solana, and building smart contracts for liquidity engines. I have also led projects that focused on zero-knowledge proofs and scaling solutions, showcasing my ability to tackle complex challenges in the blockchain space.
